Jack here, i'm new to the forums and American cars. I've always been one to do my own maintenance on my car because no one's going to take care of it as well as you do. My 2012 300 just hit about 4,700 miles and it's time for it's first oil change! Haven't seen any DIY's on this yet so i'd thought i'd post this and hopefully it'll help those who are looking to change their own oil since this is very similar to how oil changes were done on my BMW 335i.

Requirements

-6 Quarts of 5w-30
**Pictured is Mobil1 Extended Performance 5w-30 which has excellent UOA's but I just discovered that it is NOT Chrysler MS-6395 spec'd. I will be switching to Amsoil Synthetic 5W-30 for the next oil change. Don't want to give the dealerships any reason to void your warranty :P

Looking underneath there's a protective tray that needs to be removed in order to access the drain bolt. Fortunately there are only four 8mm (circled in red) bolts keeping the tray in place. Remove these then pull the tray outwards towards the rear. Slides right out!

Without the tray

Remove the 13mm bolt to drain the oil (Don't forget to unplug your oil fill cap up top for a faster drain)

Let all the oil drain out and then re-tighten the drain bolt. Leave the tray off and head up to the engine bay.

Engine Bay

Circled is the cap that holds the oil filter, remove it by using the 15/16" socket and turning counter clockwise. Once loose I prefer to hand loosen it.

Pull the old oil filter outwards to remove it. We are now going to install the new o-ring which should come with your oil filter. Pull it off and replace it with the new one.

O-Ring

Out with the old in with the new

After replacing the o-ring, place the new filter onto the cap with the prong side going into the oil cap. You should see the indentations for it and it should click into place. If installed right the filter will not fall out no matter how it's held. I usually like to apply a little bit of new oil to the filter but this is up to you. After replacing the filter and o-ring reinstall the oil filter cap.

Pour in 6 Quarts of new oil

Close the fill cap and clean up any oil with rags. Turn on your car and check for any leaks. Underneath and in the engine bay. Double check with your dipstick to make sure oil levels are correct as well. If everything checks out reinstall the tray underneath and you're done!! Congrats!!

FYI

It'd be a good idea to keep records and receipts for proof of maintenance in case the dealer decides to ask later on for warranty purposes. Have to have some kind of proof right? I just keep a log with receipts.

Feel free to comment if I may have missed something or if I could've clarified things any better. If anyone knows how to reset the oil change light please PM me or inform me so I can update this DIY. I haven't received the light yet but i'm sure it'll come on later. Also, I want to think that the 2011 is done the same way but I can never be too sure so if someone later verifies that it is or isn't I will be sure to update on that as well.
